MACHINE FOR TIGHTENING THE HEAD-HOOPS UPON BARRELS.

SPECIFICATION forming part of Letters Patent No. 756,784, dated April 5,1904.

Application filed August 31, 1903.

To all whom it may concern:

Be it known that we, THOMAS FLANERY and NELs INHITEHILL, of Minneapolis,county of Hennepin, State of Minnesota, have invented certain new anduseful Improvements in Machines for Tightening the Head-Hoops uponBarrels, of which thefollowing is a specification.

Our invention relates to barrel-making ma- :[0 chinery; and the objectof the invention is to provide a machine whereby a single attendant caneasily and quickly apply a uniform pressure simultaneously to the outeredges of barrel-head hoops to force them to their proper position uponthe ends of the barrel.

Other objects of the invention will appear from the following detaileddescription.

The invention consists generally in various constructions andcombinations, all as hereinafter described, and particularly pointed outin the claims.

In the accompanying drawings, forming part of this specification, Figure1 is a plan View of a hoop-tightening machine embodying our invention.Fig. 2 is an end elevation of the same. Fig. 3 is a front view of oneend of the machine, showing the barrel in position thereon. Fig. 4: is alongitudinal section; and Fig. 5 is a section of Fig. 4, showing the 0means for locking the barrels securely in position in the machine duringthe operation of forcing the head-hoops thereon.

In the drawings, 2 represents a suitable frame having at each end theupwardly-ex- 3 5 tending brackets 3, whereon the rock-shaft A and thefixed shaft or rod 5 are mounted.

6 represents frames or beds having longitudinally-arranged V-shapedgrooves? to receive correspondingly-shaped rails 8, whereon 4 saidframes are slidable, and provided with hooks 9 to engage said rails 8and prevent the accidental displacement of the frames 6 thereon, thoughpermitting their free horizontal movement. A rock-shaft 10 is mounted inbearings in the frame 2 and provided with cranks 11, that are connectedby rods 12 with lugs 13, depending from the under side of said frames,and said rods having turnbuckles Serial No. 171,352. (No model.)

14, by means of which their length can be increased or diminished toadjust the said frames with respect to the cranks 11. The shaft 10 isalso provided with a lever 15, by means of which the shaft 10 is rockedto move the frames 6 toward or from each other and the barrelhead. Uponthe frame 6 we provide brackets 19, having bearings 20 for shafts 21,whereon heads 22 are mounted. Each shaft is also provided with a pulley23, connected by a belt 24: with a suitable source of power. The heads22 are provided near their peripheries with a series of sheaves orpressure-wheels 25, there being preferably four in each head, and thesesheaves are arranged to revolve in planes substantially at right anglesto the plane of the heads and engage the outer edges of the headhoopsand force them toward each other to their proper position on the barrel.The pressure of the wheels on the hoops can of course be easilyregulated by means of the lever 15. A curved bed 28 is provided belowthe barrel, having suitable supports 29, that receive the barrel andcenter it between the chucks or heads. The barrel instead of revolving,as in our companion application herewith, Se rial No. 571,351,remainsstationary,the chucks bearing the pressure-sheaves revolving near thebarrel-heads.

To hold the barrel firmly in place during the operation of tighteningthe head-hoops thereon, we prefer to provide curved gripperplates 30,having toothed or roughened under surfaces to bear on the surface of thebarrel and hold the same firmly on the supports 29. These gripper-platesare pivotally connected to arms 31 and 32, the former secured to theshaft 4 by set-screws 34 and the latter ar-' ranged to turn freely onthe shaft 5. A crank 35 is secured on the shaft 4 at one end andconnected by a rod 36 with a crank 37 on a rock-shaft 38. A treadle 39is connected with the shaft 38 for operating the same to rock the shaft4 and move the gripper-plates into engagement with the barrel. An arm4L0, having an adjustable weight 41,is provided on the shaft 4 forreturning the same to its normal position and lifting the gripper-platesto release the barrel when the operator has released the treadle 39.

The operation of our machine is as follows: The barrel having beenarranged upon the supports 29, the attendant, depressing the treadle 39,will rock the shaft 4: and depress the gripper-plates sufliciently tobear upon the barrel and hold the same firmly. The lever 15 is thenmoved toward the right, and the revolving chucks or heads will be movedtoward each other until the sheaves or rollers come in contact with theouter edges of the head-hoops and pressing thereon will force them intotheir proper position on the barrel. As soon as these hoops have beenproperly tightened the operator will move the lever 15 toward 1 the leftand return the revolving chucks to their normal position, and thegripper-plates being raised by the return movement of'the rock-shaft thebarrel may be discharged, and the machine is then ready to repeat theoperation.

We claim as our invention- 1. The combination, with a suitable frame, ofa horizontal barrel-support therein, a rockshaft located above the levelof the barrel placed on said support to allow the barrel to be insertedon one side of the machine and regripper-plates carried by said arms andar ranged to engage the surface of a barrel, means for operating saidrock-shaft, and means arranged to be moved into engagement With thebarrel-head hoops and press and tighten them on the barrel.

3. The combination, with a frame, of a barrel-support, a rock-shaftmounted in said frame, arms loosely mounted on a suitable support,similar arms secured on said rock shaft, gripper-plates carried by saidarms and arranged to engage the surface of a barrel, a treadle mechanismconnected with said rockshaft and means arranged to be moved intoengagement with the barrel-head hoops to press them toward each otherand tighten them on the barrel. p

4. The combination, with a suitable frame, of a horizontalbarrel-support therein, a rockshaft located a suflicient distance abovesaid support to allow a barrel to be placed thereon from one side of themachine and removed on the other side, means for rocking said shaft,arms secured on said shaft, and gripperplates having curved facespivoted on said arms and adapted to engage the upper surface of thebarrel.

5. The combination, with a suitable frame, of a barrel-support therein,arock shaft, arms mounted thereon, gripper plates pivotally supported onsaid arms and arranged to engage the surface of the barrel, means forrocking said shaft, and means for engaging the barrel-head hoops totighten them on the barrel, substantially as described.

6. The combination, with a suitable frame, of a barrel-support therein,means for gripping the barrel, rails V-sh'aped in cross-section providedin said frame, sliding frames having grooves to fit said rails, headscarried by said sliding frames, sheaves mounted in said heads andadapted to engage the headhoops of a barrel, and means for moving saidsliding frames toward or from each other.

7. The combination, with a suitable frame, of a barrel-support therein,shafts provided above said support, one of said shafts being fixed andthe other arranged to rock in its bearings, arms loosely mounted on saidfixed shaft and secured on said rock-shaft, curved gripper-plates havingtoothed under surfaces pivotally supported on said arms and arranged toengage the surface of a barrel, a treadle connected with saidrock-shaft, and means arranged to be moved into engagement with thebarrel-head hoops to press them toward each other and tighten them onthe barrel, substantially as described.

8. The combination, with a suitable frame provided with a horizontalbarrel-support, of

a horizontal rock-shaft located a sufiicient distance above said supportto allow the barrel to be inserted on one side of the machine andremoved on the other, gripper-plates carried by said shaft, a treadlemechanism connected with said shaft for rocking the same, sliding headsor chucks having sheaves arranged to engage the head-hoops of thebarrel, and a lever mechanism near said treadle for operating saidchucks.

In witness whereof we have hereunto set our hands this 18th day ofAugust, 1908.

In presence of- RICHARD PAUL, S. V. GRIFFIN.
